  H27UCG8T2FTR-BC is similar to the already-supported H27UCG8T2ETR-BC, but
reports a different ID.

Can you provide a datasheet for this part? I am surprised by the page
size. In general anyway, it's best to provide a link when adding
support for a new component.

Also, for your two series, no need to resend this time, but please use
git-format-patch and git-send-email to create your series, so that all
the patches are answers of the cover letter. It helps keeping all
patches and answers in the series packed together.

Thanks!

You can ignore this, I did momentarily change the display inadvertently
on my side, your series are perfectly fine.

Sorry for the noise.

I was unable to find a datasheet for specifically H27UCG8T2FTR-BC. The
best datasheet I could find is for H27UCG8T2ETR-BC[0][1]. However, there
are layout parameters for H27UCG8T2FTR-BC in some versions of the vendor
NAND driver[2][3][4]. The Hynix chip is packaged as Essencore
I3T-8GQ8T2H5TARC, as referenced in that NAND ID table, which is the
actual package on the board I have.

Regards,
Samuel

Pointing to [0] or [1] in the commit log would be nice at least, even
though we cannot get our hands on the real datasheet...

This and what is displayed in the two datasheets pointed above looks
very much like out-of-band data to me, I don't get why we should treat
this part of the array differently? The OOB area is not only supposed to
be used for ECC bytes (even though that's how UBI make use of it), you
can store all the data you want there (but it's not necessarily
protected by the ECC engine, which, in general, matters a lot.

I don't see how this datasheet would be different than the others. They
don't detail the geometry, I would have expected them to do it if the
page size was anything different than the standard?

Maybe we are misunderstanding each other. The page size I have declared
in the table is SZ_16K, which I believe is a standard value. The
non-power-of-two chip size comes from the number of blocks in the chip;
the ".blk_cnt_per_die = 2112" above corresponds to the "8448" in patch 3.

For H27UCG8T2ETR this is described in the datasheet on page 3 as "1,060
blocks x 2 plane" and "(1,024 blocks + 36 block)/1plane". These extra
blocks are separate from the OOB area inside each page.

Samuel

Oh right, sorry I messed things up in my mind. So yes it's a real
situation. If we grep chip_shift and pagemask there are a number of
users (controller drivers) which might actually be impacted. We need to
be careful. Right now I am not sure we should we should play with the
core to support these extra blocks...
